Installation
Manual 1866 Rev A p/n 1866
Length of the Connection Pipes
With connection pipes that have the same pipe
cross section as the machine connection and area
more than 3m long, a non-return valve must be
installed in order to avoid reverse operation when
the machine has stopped.
Exhaust Air Must Not be Restricted
Do not block the exhaust pipe of the pump
(maximum discharge pressure is 22.5 Torr or 30
mbars). When the exhaust air pipe is connected it
must be checked regularly for impurities.
Material damage resulting from the forces and
torques of the pipes on the unit being too high.
Only screw pipes in by hand.
Do not operate without the standard
regulating and relief valve.
If the permissible
vacuum is exceeded (see data plate) the
machine may be damaged.
CONNECTING THE MOTOR
DANGER
!
Danger of death if the electrical
installation is not professionally
completed. The electrical
installation must be completed by
a qualified electrician observing
EN 60204. The operating
company is required to provide
the main switch.
The motor’s electrical data is given on the data
plate or on the motor data plate. The motors
comply with DIN EN 60034 and are in protection
class IP55 and insulation class F. The appropriate
connection diagram is located in the motor’s
terminal box (not for the plug connection version).
The motor data must be compared with the data of
the existing mains network (current type, voltage,
network frequency, and permitted current value).
Connect the motor via the plug connection or
the motor overload. For safety reasons, a motor
overload is required and the connecting cable
must be installed via a cable fitting to provide
strain relief. Kinney recommends using motor
protection switches with delayed switch off,
depending on possible excess current. Temporary
excess current may occur when the machine is
started cold.
Power Supply
The conditions at the installation location must
match the information on the motor data plate.
Without derating the following is permissible:
• ± 5% Voltage deviation
• ± 2% Frequency deviation
